Kernel Panic - not syncing: Attempted to kill init!

Kernel Panic - not syncing: Attempted to kill init!

[Sreen Tallam]

Hi All,

Has anyone seen this error?
I am running a 2.6.18 kernel on a PPC 405GP using a AMCC Walnut board.

I added some printf's within the kernel to debug more information, and
it pointed to

init/main.c
under init() routine
in run_init_process(execute_command);
where execute_command = /sbin/tallam_init

This looks like you are missing /dev/console and probably /dev/null. You
need atleast those two nodes in your rootfs if you are using udev. You
will need a static /dev if you don't use udev/mdev.

Hi Sebastian,

Thank you for looking into this issue.
But I am not using udev. And my /dev is empty, there is no devices in there.

Any more hints on this. I would appreciate your follow up.

Thanks,
Sreen
